Utah has three dangerous spiders, The Hobo, Black Widow and Yellow Sac Spider. The following bio is provided by www.hobospider.org by Darwin K. Vest from Eagle Rock Research.The following covers the identification, habitat and the bites of these spiders.
Utah has two species of Pocket Gophers, the Northern Pocket Gopher and the Botta (southern and central Utah) Gopher. Gophers have a poor vision which is compensated by other senses such as hearing, smell, and touch.
Gopher damage can be identified mostly by the soil mounds they leave behind as evidence of the tunneling system under your yard. The mounds are shaped like a semi-circle and the entrance is sealed with a soil plug. The tunnels below the surface range from 4-18 inches deep and they are interconnected. The damage caused by a single Pocket Gopher can be enormous. A single gopher will create 300 mounds in their lifetime, moving 4 tons of soil from location to location.
Gophers are active year round. In the winter months they tunnel through the snow. They eat only plant materials such as grass & Alfalfa. Dandelion roots are especially their favorite snack.
The Utah State University's Plant Pest Diagnostic lab gives some excellent tips that home owners can do to protect their yard from gophers:
